Dear GS Sandhu,
Julie and I have read your essay and we really liked your clear distinction between mathematical abstractions and physical reality. It's easy to accidentally blur this line and we think your clarity on this is very important when working on fundamental topics. We are also in agreement with the position you take about the nature of space, time, and causality. We defend compatible views in our essay, where we propose a model in which space is a kind of medium that has energy and can interact with physical matter, just as you argue must be the case. We were also pleased to see you defending the view that the future comes about through the operation of physical laws of nature operating in the present. Taking causation and change seriously is important for doing clearheaded science. We also rely on this approach in our essay, where we argue that a commitment to scientific explanations inevitable commit us to conservation laws, causal processes and genuine change.
Congratulations on a very well written essay that defends important fundamental concepts and distinctions, and proposes practical tests of the ideas you propose. We like your essay very much, and we have rated it very positively.
Best wishes,
David and Julie
